Missing required icons, While submitting app via Application Loader


I have successfully packed my app. But when i try to upload it via Application Loader it gives me following error.

ERROR ITMS-90236: “Missing required icons. The application bundle does not contain an icon in ICNS format, containing both a 512x512 and a 512x512@2x image. For further assistance, see the Apple Human Interface Guidelines.”

I am packaging app using “electron-packager”. Following is the application packaging script.
electron-packager . applicationName --platform=darwin --arch=x64 --icon=icon/icon.icns --ignore=node_modules/* --out=/output/path

Any help on this topic will be appreciated. I am desperate to upload my app on app store.



Try this app:

Or this script:


What was your solution at the end, I have the same errors. Do we need to add an entry in the Info.plist?


Ok found a post on stackoverflow:

I didn’t know that the icns format is actually many resolutions in one file.
